Annealing thiab normalizing yog ob feem ntau siv cov kev kho cua sov uas muaj cov txiaj ntsig zoo rau cov ntaub ntawv. Hauv tsab xov xwm no, peb yuav tshawb txog qhov sib txawv ntawm cov txheej txheem no thiab lawv cov ntawv thov.
Annealing yog cov txheej txheem kev kho cua sov tsom rau cov ntaub ntawv softening, txo cov kev ntxhov siab sab hauv, thiab txhim kho lawv cov machinability thiab ductility.
01
Txheej txheem:
Cua sov: Cov khoom raug coj mus rau qhov kub thiab txias uas siab tshaj qhov kub tseem ceeb.
Soaking: Cov khoom yog tuav ntawm qhov kub thiab txias rau lub sijhawm ntev kom tso cai rau kev hloov pauv yam xav tau.
Txias: Cov khoom yog txias maj mam thiab ua tib zoo, tsis hais nyob rau hauv lub cub tawg los yog muab faus rau hauv ib yam khoom uas thaiv cua sov, xws li tshauv lossis xuab zeb.
02
Daim ntawv thov:
Annealing muaj ntau daim ntawv thov nyob rau hauv ntau yam lag luam, nrog rau hlau, alloys, thiab iav.
03
Cov txiaj ntsig:
Txhim kho machinability: Annealing softens cov khoom, ua rau nws yooj yim rau tshuab, tsim, thiab zoo li.
Kev ntxhov siab: Nws pab txhawm rau txo cov kev ntxhov siab sab hauv uas raug ntxias thaum lub sijhawm ua haujlwm xws li vuam lossis ua haujlwm txias, txo qhov kev pheej hmoo ntawm cov khoom tsis ua haujlwm.
04
Cov txiaj ntsig:
Grain structure refinement: Annealing txhawb kev tsim cov qauv zoo thiab zoo ib yam, ua rau cov khoom siv kho kom zoo dua qub thiab txo cov brittleness.
Recrystallization: Nws pab txhawb cov recrystallization ntawm cov ntaub ntawv deformed, txhim kho lawv cov hluav taws xob conductivity thiab sib nqus zog.
normalizing
Normalizing yog lwm cov txheej txheem kho cua sov siv los kho cov microstructure, txhim kho cov khoom siv kho tshuab, thiab txo cov kev ntxhov siab hauv cov ntaub ntawv.
Txheej txheem
Cua sov: Txhawm rau kom ua tiav qhov ntsuas kub tsis sib xws, cov khoom siv yog rhuab saum nws qhov kub thiab txias.
Soaking: Cov khoom yog tuav ntawm qhov xav tau kub kom ua tiav cov qauv austenitic tag nrho.
Txias: Cov khoom yog txias hauv cov huab cua tseem ceeb ntawm tus nqi tswj, feem ntau sai dua annealing tab sis qeeb dua quenching.
Daim ntawv thov
Nws yog dav siv nyob rau hauv zus tau tej cov steels siv nyob rau hauv kev tsim kho, machinery, thiab automotive industries, pab txhawb lawv lub zog thiab durability.
Cov txiaj ntsig
Grain Structure Refinement: Normalizing pab ua kom zoo dua cov qauv ntawm cov khoom, ua rau muaj zog, tawv, thiab sib xws.
Kev ntxhov siab: Nws txo cov kev ntxhov siab hauv cov ntaub ntawv, txhim kho lawv txoj kev ruaj ntseg thiab txo qhov kev pheej hmoo ntawm kev cuam tshuam los yog tawg.
Cov txiaj ntsig
Kev tshem tawm txawv txav: Normalizing feem ntau yog siv rau hauv castings thiab welded Cheebtsam kom tshem tawm cov txheej txheem txawv txav, txhim kho homogeneity, thiab txhim kho cov khoom siv kho tshuab.
Hauv kev xaus, ob qho tib si annealing thiab normalizing yog cov txheej txheem kho cua sov uas muaj txiaj ntsig zoo. Annealing feem ntau yog tsom rau kev txhim kho machinability thiab ductility thaum normalizing lub hom phiaj los ua kom zoo dua microstructure thiab txhim kho cov khoom siv kho tshuab. Kev nkag siab txog qhov sib txawv ntawm cov txheej txheem no tso cai rau kev txiav txim siab hauv cov khoom siv thiab kev tsim khoom lag luam.
